lMPROVEMENT IN CULTli/ATORS.

Specieation forming part of Letters Patent No. 122,400, dated January 2, 1872.

SPECIFICATION.

l, OSCAR L. NEIsLER, of Indianola, in the county of VaI-ren and State of Iowa, have invented certain Improvements in Oultivators, of which the following is a specification:

My invention is designed to form and mount double cultivators in such a manner that the complete machine will be more com pact, closer to the horses, and requiring less drait than usual; to form and combine the mounted frame and the eultivators so that there will be no rigid strain on either part, while adjustment and independent lateral and vertical play are freely allowed. It consists: First, in extending thc beams forward and beyond the aXis ofthe wheels and connecting them with the evener. Sccond,in makingjointed beams. Third,each and every part, as hereinafter fully set forth.

Figure 1 ot' my drawing is a perspective view, illustrating the manner in which my cultivator is formed, combined, and operated.

A A is the cross-bar of the carriage, framed and bolted to the pole B B. C C is the horizontal bar of the evcner. l) D is the combined upright and stud-axle, made of cast or wrought metal. Two or more open spaces, extending from top to bottom, are formed in the upright for the admission ofthe beam. Bolts with open ends or eyes are used to hold the upright to the crossbar. By means ofthe nuts above the cross-bar the uprights can be tightly drawn and rigidly held to the cross-bar, and when it is desired to change the distance between the Wheels the eyebolts can be let down (as reppresented at the right end of the cross-bar) and the uprights Inoved in or out to accommodate the wheels to the various distances between the rows of cornor other plants. 1n place of the eyebolts slots or eyes may be formed in the horizontal top bar of the upright, and common bolts with large heads passed upward through these slots and through the cross-bar. E E are curved iron braces, connected with the stud-axles and the pole B B. Their upper ends pass in reverse ways through the eyebolt, which holds them to the pole. By this means these braces can be lengthened and shortened, as required, when the distance between the wheels is enlarged or diminished. G G is a swinging frame and part of the evener hinged to the horizontal bar C C.

The uprights of this swinging frame contain holes for the purpose of lowering and raising the draft-hook li, and also the rod J, with which the end of the beam is connected. K K K is the jointed beam. The front end is formed of a single piece, and is pivoted orlinlted to the rod J. lyraising and lowering this rod J in the swinging frame Ur Gr the depth ofthe plowing can be regulated. ',lhe front end of the beam passed through one ot' the open spaces in the upright l) l) is free to move np anddown and back and forth, but is prevented from all twistingl and lateral motion. A pin or its equivalent prevents the beam from passing too far forward through the upright. A suitable device may be connected with the cross-bar, and pendant from it, by which the beam can be raised and lowered and held at any elevation desired. The rear end of my b 1.am is double or bifureated, and is hinged to the front part in such a manner that the joint provides lateral play for the eultivator. The handle and the standards withthcir shovels are bolted and braced, in a common way, directly to the forked ends ot' my `jointed beam.

By means of the jointed beams l get perfect control of the lateral motion of the cultivators.

Ordinarily cultivators have too much lateral motion and are with difficulty kept in a straight line. When a lateral motion is required it should generally be a short and quick turn, such as cannot well be made when a long rigid and solid beam is used. The ,jointed beams also allow me to bring the cultivators close to the frame and to the horses, and to communicate the draft from the horses directly to the cultivators through a linked and yielding chain, composed of the draft-hook H, the swinging frame G G, and the movable front end ot' the beam. The frame or Carriage is thus almost entirely relieved of strain and the work ofthe horses is materially lightened. B y moving the Wheels, and also the front ends of the beams in and ont to conform to the space between the rows, and by eontining the lateral motion to the short and forked end of the beam, the operators duty is made simple and easy.

.l am aware that plows or shovels have been hung toabeam or axle running at right angles with the line of draft and connected by means of a swivel joint to two drag-bars attached to thcaxleof thecarriag'e. My jointedbeam runs parallel with the line ot' drai't, and cach cultivalor has its own independent beam, composed ot' the straight front end and the rear forked or hil'urcuted end. I am aware that attachments similar to mine, and designed for the same purpose, have been used; but l claim that my attachment is in an improved and peculiar form, and that it is advantageous to use a common straight holt in place ot' n hooked bolt and a staple.

u a is the attach in en t, ma de of castor Wrou ght metal. It isol' nearly diamond form, flat, and curved. 1t hasncrescent-shaped opening in its center, with the points standing upward.y The upper edge ot' this. opening.; han` two or more slots, through which ulholt ma)V pass. The form and size of this attachment and its crescentshaped center opening;` ma)Y be varied. VWashers or their equivalents on the rivets hold the attachment ott' from immediate Contact with the shovel and provide space for the head of the holt b. The holtcan be placed in its proper place in the end ot' the standard, and bymeans of' myattaehment the shovel can be connected, adjusted, or removed Without withdrawing the bolt from the standard by simply passing the head of the bolt through the crescent opening and allowing the neck ot the bolt to enter one of the slots in the upper edge, and then drawnL ing,` or loosening` the bolt by means of the nut on its outer end. A simple and complete device is thus provided, by the use of which the shovels can be set and regulated to throw the loose ground to the right or left, as desired.

Claim.

Passing the front end of my jointed beam K through one of the open spaces in the frame D and connecting the same with the evener E, in the manner described, as a means of preventing the beam from lateral movement and at the same time allowingit free backend-forth and lip-and-down motion.
